Innovation Solution

A method utilizing a recording device with a front-facing camera and a rear-facing camera or safety device for face recognition, combined with additional biometric scanners, generates and verifies user identifiers as metadata, secured by blockchain technology, ensuring creator identification and preventing unauthorized use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automated user identification is implemented using existing methods, then creator assignment is simplified, but forgery safety and reliability are insufficient

Engineering Contradiction:
Improveautomated user identificationVSAvoidforgery safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent changes the identification parameter from simple metadata or username to biometric data (facial recognition features, iris patterns, fingerprint characteristics). This parameter change fundamentally increases forgery safety while maintaining automated operation, as biometric traits are unique and difficult to replicate compared to conventional identification methods.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces mechanical/conventional identification systems (manual entry, simple camera verification) with advanced biometric verification systems. The recording device integrates multiple sensors (camera, iris scanner, fingerprint scanner) that automatically capture and verify biometric parameters, substituting manual or simple automated processes with robust biometric authentication.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If multiple safety verification methods are implemented, then forgery safety is improved, but device complexity increases

Engineering Contradiction:
Improveforgery safetyVSAvoidsafety device structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple safety verification functions (facial recognition, iris scanning, fingerprint detection) into a single integrated recording device. The control unit coordinates all these functions through a unified system, allowing the device to select and execute appropriate verification methods based on the situation, thereby reducing operational complexity despite the presence of multiple safety mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The recording device is designed with multi-functionality, serving both as a media recording device and a biometric verification system. The same device captures media files and performs creator identification, eliminating the need for separate verification devices and reducing overall system complexity while maintaining high security standards.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If biometric verification is performed during recording, then creator identification accuracy is improved, but processing time increases

Engineering Contradiction:
Improvecreator identification accuracyVSAvoidverification processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs biometric verification during the recording process itself, rather than as a separate post-processing step. The control unit continuously monitors biometric parameters throughout the recording period, ensuring creator identification occurs in real-time. This preliminary action prevents time loss by integrating verification into the existing recording workflow.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The biometric verification operates continuously during the entire recording process, maintaining constant monitoring of creator identity. This continuous verification ensures that if the creator changes during recording, the system can detect and respond to it immediately, maintaining high identification accuracy without requiring separate verification intervals that would interrupt the recording.

Inventive Principle:
Principle #20Continuity of useful action
